Abstract

In this paper, we propose an efficient method to estimate the end-to-end Available Bandwidth (AB) of a network path. This method employs multi-rate (MR) probe packet sequences with Kalman filtering. Our proposed method is an extension of the Bandwidth Available in Real Time (BART) method, so that the probe packet sequences are injected into the network path of interest. Using this technique, the probing rate within each probing sequence is varied. We show that by a marginal addition to the computation complexity compared to the conventional BART technique, the proposed method converges faster than that of BART and achieves a more accurate estimation. In addition, this method is more robust against inappropriate initial value of Kalman filter than the conventional BART method. Furthermore, we obtain the estimation error of MR-BART based on the parameters of the probe packet sequences.
